Product details
Overview
CY9BF114NPMC-GE1 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 microcontroller designed for motor control and industrial embedded systems. It operates up to 144 MHz, integrates 512 KB MainFlash with Flash Accelerator, 32 KB WorkFlash, 64 KB SRAM (split into two 32 KB banks), and features dual 12-bit ADCs (16 channels total), eight base timers, three QPRC channels, and LIN/UART/I²C/CSIO serial interfaces.
For engineers reviewing the CY9BF114NPMC-GE1 datasheet, CY9BF114NPMC-GE1 pinout, CY9BF114NPMC-GE1 application, or CY9BF114NPMC-GE1 equivalent, key selection criteria include its 144 MHz Cortex-M3 core, dual Flash architecture with security protection, 5 V-tolerant I/O support on selected pins, RTC with leap-year handling, and integrated motor-control peripherals including dead-time insertion and DTIF interrupt.
Technical Context
This MCU implements the Arm Cortex-M3 r2p1 core with Memory Protection Unit (MPU) and NVIC supporting 48 peripheral interrupts across 16 priority levels. Its dual-bank Flash architecture enables secure code execution and background reprogramming: MainFlash delivers zero-wait access up to 72 MHz, while WorkFlash supports configurable wait states (0–4) depending on operating frequency.
The peripheral set targets real-time motion control: three multi-function timers provide PWM, PPG, input capture, and A/D activation; three QPRC units directly interface quadrature encoders; and LIN 2.1 support includes programmable break field (13–16 bit) and delimiter (1–4 bit) generation for automotive body electronics compliance.

Pinout & Package
The CY9BF114NPMC-GE1 is housed in a 120-pin LQFP package (14 mm × 14 mm, 0.4 mm pitch) with exposed thermal pad. Pin functions include 103 general-purpose I/Os (some 5 V tolerant), dedicated motor control signals (e.g., PWMxH/PWMxL, DTIF), QPRC inputs (AIN/BIN/ZIN), and multiple clock/reset domains (MAINCLK, SUBCLK, INITX).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P07 | General-purpose I/O / Port 0 | Configurable as GPIO or remapped peripheral functions (e.g., UART0_TX/RX, CSIO0_SCK) |
| P10–P17 | General-purpose I/O / Port 1 | Supports 5 V tolerance; used for LIN transceiver interface and external interrupt inputs |
| P20–P27 | Motor Control I/O | Directly drive PWMxH/PWMxL outputs with programmable dead time and DTIF emergency stop signal |
| AIN0/BIN0/ZIN0 | QPRC Channel 0 Inputs | Dedicated quadrature encoder interface with edge-detect configuration and 16-bit position/revolution counters |

|---|---|
| Flash Accelerator with 16 KB trace buffer | Enables zero-wait Flash access at ≤72 MHz and maintains effective bandwidth above 72 MHz via prefetch and caching |
| Motor Control Timer with DTIF | Hardware-implemented emergency stop signal that forces all PWM outputs low within one clock cycle upon fault detection |
| LIN 2.1 Protocol Engine | On-chip LIN frame generation and validation - eliminates software overhead for checksum, sync, and identifier fields |
| Port Relocation Function | Allows dynamic assignment of peripheral functions (e.g., UART, CSIO) to alternate GPIO pins without PCB redesign |
| Two-stage Low-Voltage Detector (LVD) | LVD1 triggers interrupt for graceful shutdown; LVD2 asserts reset to prevent corrupted Flash writes during brownout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303VCT6 | ARM Cortex-M4F core, 72 MHz max, 256 KB Flash, no integrated LIN PHY, single 12-bit ADC (16 ch) | Lacks native LIN 2.1 support; requires external transceiver and software stack for LIN communication | Preferred when floating-point math or DSP instructions are required, but adds BOM cost and design complexity for LIN networks |
| RA4M1 (R7FA4M1AB3CFM) | ARM Cortex-M4 core, 48 MHz, 256 KB Flash, 32 KB SRAM, no QPRC, no DTIF hardware | No dedicated motor emergency stop signal; QPRC functionality must be emulated in software using general-purpose timers | Selected for lower power consumption in battery-backed applications where motor safety-critical timing is managed externally |
Compared with STM32F303VCT6 and RA4M1, the CY9BF114NPMC-GE1 uniquely combines 144 MHz performance, hardware LIN 2.1, DTIF, and triple QPRC in a single 120-pin LQFP - reducing system-level timing uncertainty and eliminating external safety logic in industrial motor drives.

FAQ
What is the maximum operating frequency of the CY9BF114NPMC-GE1 core?
The Arm Cortex-M3 core operates at up to 144 MHz, enabled by the internal Main PLL driven by either an external 4–48 MHz crystal or the 4 MHz high-speed internal CR oscillator. This frequency is sustained across the full operating voltage range (2.7 V to 5.5 V) and ambient temperature range (–40 °C to +105 °C), as verified in Section 12.4.4 of the datasheet.
Does the CY9BF114NPMC-GE1 support hardware LIN 2.1 communication without external transceivers?
The CY9BF114NPMC-GE1 integrates a full LIN 2.1 protocol engine with programmable break field (13–16 bit), delimiter (1–4 bit), and checksum generation - but requires an external LIN physical layer transceiver (e.g., TLE7259-3GE) to drive the bus line. The MCU handles all protocol-layer tasks in hardware, minimizing CPU load and jitter.
How many independent PWM outputs with dead-time insertion does the CY9BF114NPMC-GE1 support?
The device supports up to six independent high-side/low-side PWM output pairs (PWMxH/PWMxL) with fully programmable dead-time insertion per channel, implemented in dedicated motor control timers. Each pair can be configured with independent polarity, period, and duty cycle, and all outputs are subject to immediate forced-off via the DTIF emergency stop signal.
Is the RTC in the CY9BF114NPMC-GE1 battery-backed and capable of maintaining time during Stop mode?
Yes - the RTC operates from the 32.768 kHz SUBCLK source and continues counting in Stop mode when powered by a backup supply (VBAT). It retains full functionality including alarm interrupts, periodic wake-up, and leap-year correction, with time values preserved across power cycles when VBAT is present and ≥1.8 V.
